Hexagram 21, Shì Kè (Biting Through): Line 6 (top)
噬嗑卦上九 · 火雷噬嗑 · 中文版
上九：何校灭耳，凶。
The line (Legge)
The sixth NINE, undivided, shows one wearing the cangue, and deprived of his ears. There will be evil.
Small Image commentary
'He wears the cangue and is deprived of his ears:' - he hears, but will not understand.
象曰：何校灭耳，聪不明也。
In plain words
Wearing a cangue that hides the ears: misfortune. The top line is at the height of the hexagram: its offence is great, and it will not listen to warnings. The Small Image says its hearing is not clear. The Great Commentary says that when wrongs pile up they cannot be hidden, and when the offence is great it cannot be undone.
Applying it to your situation
This line is a reminder to take advice. Is there advice you have never let in?
Position
A solid (yang) line in the top place, which is a yin (even) place, so it is not in its proper place. Its partner is line 3; one is yin and the other yang, so they respond to each other.
If this line moves
With this line moving alone, Shì Kè changes into Hexagram 51 Zhèn (The Arousing Thunder). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·噬嗑之震.
The hexagram
Hexagram 21 Shì Kè (Biting Through). The Judgment: Shi He indicates successful progress (in the condition of things which it supposes). It will be advantageous to use legal constraints.
